Evaluation of design meteorological day for air-conditioning load calculation based on indoor environmental risk level

摘要：

　　The concept of indoor environmental risk level(IERL)is proposed to determine the design weather conditions for air conditioning load calculation from the perspective of indoor environment.The relationship between building parameters(window-wall ratio and ventilation rate)and indoor environmental risk level was established based on the 30 years hourly weather data of Guangzhou,Shanghai and Tianjin.Under the same cooling load,the risk level fluctuation index(F)is used to evaluate the design meteorological day(DMD)and the real meteorological day(RMD).The results show that the current design weather parameters are inconsistent with near-extreme weather characteristics,and make the proportion difference between the design load and hourly load,which will lead to the IERL varies with ventilation rate and window-wall ratio.However,IERL based on RMD remains essentially unchanged.
